Jack Osbourne announces engagement to actress Lisa Stelly

The former reality television star, who directed a documentary about his famous father Ozzy earlier this year, proposed to actress Stelly recently. Jack's spokesperson confirmed the engagement to E! News earlier today.

A source also has told Us Weekly that Jack is a "great influence on her", adding: "It's just no drama. More stable".

Last year, the 25-year-old was rumoured to be dating fashion model Sarah McNeilly. An insider confirmed that the couple celebrated his birthday together in Las Vegas and said at the time: "They're very much on, full speed ahead. They seem super into each other! Both seem very happy."

Osbourne has also previously been linked to former Hollyoaks actress Gemma Atkinson, Rod Stewart's daughter Kimberley and model Kate Moss.

Jack's sister Kelly got engaged to model Luke Worrall in 2008, but they split in 2010 over rumours that he cheated on her up to six times during their relationship.

Kelly recently praised her brother for helping their father Ozzy get clean, saying: "Jack changed a lot of things when he changed himself [and stopped drinking], and it's hard for a father to look at his son and say, 'If he can do it, how come I can't?'"
